    • The 2,6-dichlorophenyl-substituted amino-imidazole derivatives 1-(2',6'-dichlorophenyl)-2-amino-4-methyl-imidazole, 2-(2',6'-dichloroanilino)-4-methyl-imidazole, their non-toxic, pharmaceutically acceptable, acid addition salts and mixtures thereof, exhibit excellent anti-hypertensive activity which makes the derivatives particularly suitable for treatment of high blood pressure in mammals.The derivatives may be prepared in either of two processes. The first process involves the sequential reaction of a known starting material with ammonia and a halogenated acetone which may be followed by separation of the formed isomers. The second process involves the decarboxylation of the novel intermediates 4-[1-(2',6'-dichlorophenyl)-2-amino)]-imidazoleacetic acid or 4-[2-(2',6'-dichloroanilino)]-imidazoleacetic acid or mixtures thereof. Such intermediates, their lower alkyl esters, their non-toxic, pharmaceutically acceptable acid addition salts or mixtures thereof may also be employed as a diuretic agent.The derivatives are employed in an effective amount and are typically combined with a pharmaceutical carrier. Administration of the derivatives may be accomplished either orally or parenterally.
    • 2,6-二氯苯基取代的氨基咪唑衍生物1-(2',6'-二氯苯基)-2-氨基-4-甲基咪唑,2-(2',6'-二氯苯胺基)-4-甲基 - 咪唑,它们的无毒,药学上可接受的酸加成盐及其混合物表现出优异的抗高血压活性,这使得该衍生物特别适用于治疗哺乳动物的高血压。 衍生物可以以两种方法中的任一种制备。 第一种方法是将已知原料与氨和卤代丙酮进行顺序反应,然后分离所形成的异构体。 第二种方法涉及新型中间体4- [1-(2',6'-二氯苯基)-2-氨基)] - 咪唑乙酸或4- [2-(2',6'-二氯苯胺基)] - 咪唑乙酸或其混合物。 这样的中间体,它们的低级烷基酯,其无毒的,药学上可接受的酸加成盐或其混合物也可以用作利尿剂。 衍生物以有效量使用,通常与药物载体组合。 衍生物的施用可以口服或胃肠外实施。
